Subscribing to Podcasts with Tweety

I reviewed EPN and Pod Alley was frustrated by how many podcasts were no longer available. Then I ran through a few which were not of good quality. I guess I am hard to please. I finally stubbled on EPN's DreamExtreme. I liked the concept of working with students on different subjects, allowing them to report out, knowing they had to do the research. I also liked the theme in their song and would like to teach it to a group of students. I have found another use for podcasts. I also viewed several videocasts and still have a preference for them. Perhaps other users who have found quality podcasts can share them.
